MRI

In a study involving over 2,800 people who had brain MRI scans, researchers found that people in the most disadvantaged neighborhoods had 37 percent higher white matter hyperintensity volume (WMHV) on average in comparison to people in the least disadvantaged areas.

The presence of vascular hyperintensity on T2 FLAIR MRI was associated with nearly double the odds of cerebral edema, according to newly published research involving 855 patients with acute ischemic stroke.

New research demonstrates significantly higher specificity and inter-reader agreement with MRI-guided reconstruction in comparison to standard ordered-subset expectation-maximization (OSEM) reconstruction of PET imaging for amyloid assessment.

New research suggests that photon-counting CT provides comparable sensitivity to breast MRI for lesion characterization, higher accuracy than MRI for nodal metastasis and lower detection of microcalcifications in comparison to full-field digital mammography.

This summer's breast imaging research spanned digital breast tomosynthesis (DBT) efficiency gains, AI models that flag cancer risk years before diagnosis, a cautionary study on automation bias, and advances in ultrasound, MRI, and contrast-enhanced mammography (CEM). Here is a look back at the most well-viewed breast imaging content of the summer.

For patients who had successful reperfusion after acute ischemic stroke, new research demonstrated an 80 percent AUC for predicting infarct with the combination of apparent diffusion coefficient (ADC) mapping and relative oxygen ejection fraction (rOEF).

New research revealed that risk-stratified MRI surveillance in patients with cirrhosis led to over a 10 percent increase in early detection and over a 44 percent decrease in surveillance exams in comparison to reported results with semiannual ultrasound monitoring.

Catch up on the latest blogs from Filippo Cademartiri, MD, PhD, who discusses topics ranging from CCTA scan acquisition and photon-counting CT to artificial intelligence and assessment of current plaque as a biomarker for evaluating MACE risk.

In comparison to standard readout-segmented echo-planar imaging, the combination of deep learning reconstruction and multi-shot diffusion-weighted imaging (DWI) offered significantly higher SNR, CNR and lesion contrast with a greater than a two-minute reduction in scan time.

Noting the rising imaging volume and dearth of MRI scanner availability, the authors of a new literature review explore the utility and impact of workflow redesign, staff training, scheduling improvements and AI advances for enhancing MRI workflows.

Smaller voxel size may offer insights into biology we could never access with conventional resolution.

In a recently published review of the BI-RADS v2025 manual, leading breast radiologists offered pertinent insights on key changes for reporting of mammogram, breast ultrasound and breast MRI interpretation and assessment.

In a recent interview, Kay Jann, PhD, discussed challenges with urinary continence in stroke survivors and a forthcoming NIH-funded study examining the use of brain MRI to help identify those who may benefit from transcutaneous spinal cord stimulation (TSCS).

In comparison to 2023 statistics, the authors of a new study noted an approximately 49 percent increase in radiology turnaround time for ultrasound interpretation and over a 35 percent increase in turnaround time for X-ray assessments.

Extracellular volume fraction (ECV) assessment with photon-counting CT offered higher sensitivity and comparable specificity and AUC to magnetic resonance elastography (MRE)-derived liver stiffness measurement (LSM) for evaluating patients with stage 2 or higher fibrosis, according to a recent study.

A model combining MRI and ultrasound findings yielded a 93 percent AUC for predicting microvascular invasion in hepatocellular carcinoma.

In a recent interview, Vivek Singh, MD, discussed the practical realities of integrating AI into neuroradiology workflows, addressing challenges and concerns with implementation and potential automation bias, and emphasizing the importance of appropriate governance with AI tools and measurable outcomes in stroke imaging.
